<p>The present invention is directed to an adhesive composition comprising a crosslinkable acrylic copolymer, a multi-functionalized crosslinkable oligomer and a photoinitiator wherein the composition exhibits excellent wet out characteristics as reflected in a tan delta value of at least 0.5, preferably greater than 0.5, more preferable greater than 0.8 as measured at 20 °C resulting from a first curing stage, and improved stiffness and temperature resistance as reflected in a storage elastic modulus of at least 300,000 Pa at 20 °C and a shear adhesion failure temperature of at least 425 °F (218.3 °C) at 1 Kg/in 2 (0.155 Kg/cm 2 ), respectively, which result from a second sequential curing stage.</p> |
